Fasting free fatty acids (FFA), plasma cortisol (F) were determined in newly diagnosed patients with type 2 diabetes. The results show that FFA, F and HOMA-IR are significantly higher in patients with type 2 diabetes than those in controls(all P

Idiopathic rapid eye movement (REM) sleep behavior disorder is recognized as a prodromal stage of α-synucleinopathies such as Parkinson′s disease, Lewy body dementia and multiple system atrophy. It is important to timely identify early predictors that can predict early conversion into α-synucleinopathies. This review provided an update on classic and novel early predictors of α-synucleinopathies in patients with idiopathic REM sleep behavior disorder and provided a comprehensive understanding on the phenotypic transformation of the disease.

Objective To explore the role of T cell-mediated immunity in the pathogenesis of venous thromboembolism ( VTE ) by analyzing the differential expression of T cell immune-related gene mRNAs peripheral blood mononuclear cells (PBMCs) between VTE patients and controls with GeneChip Human Genome. Methods Human eDNA microarray analysis was employed in PBMCs from 20 VTE patients and 20 hypertensive controls,and random variant model (RVM) corrected t-test was used for statistical analysis of differential gene expression.Results Six mRNA stripes including CD247,CD3D,CD3G,Granzyme A (GzmA),Granzyme B (GzmB) and Zeta-chain-associated protein kinase 70 (ZAP70)were found to be associated with T cell-mediated immunity.Significant down-regulation of these six mRNAs was found in the VTE group compared with the controls ( 15.3050 ± 0.6346 vs 15.8053 ± 0.5567,13.7878 ±0.7731 vs 14.3820 ±0.4857,13.3299 ± 0.9104 vs 14.1246 ± 0.6011,14.8893 ± 0.8675 vs 15.5305 ±0.4624,15.9113 ±0.8123 vs 16.4553 ±0.5055,14.3652 ±0.7717 vs 14.3652 ±0.7717;all P values ＜ 0.05 ).Conclusions T cells' function including antigen recognition,signal transduction and cytotoxicity was impaired in VTE patients.T cell-mediated immunity dysfunction probably plays an important role in the pathogenesis of VTE.

Objective To investigate the clinical significance of changes in lipids and apolipoproteins (Apo) in type 2 diabetic patients and their normoglycemic first-degree relatives (NFDR). Methods Triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), ApoAⅠ, ApoB_ 100 , ApoCⅢ and ApoE were determined in 62 type 2 diabetic patients and 67 NFDR from 29 Chinese type 2 diabetic pedigrees as well as 45 normoglycemic controls without family history of diabetes (NC) in Chengdu city, China. Results (1)TG level was higher in type 2 diabetic patients 〔(1.85?1.31)mmol/L〕 as compared with those in NFDR 〔(1.39?0.91)mmol/L〕 and NC 〔(0.92?0.45)mmol/L〕, and TG level in NFDR was higher as compared with that in NC (all P

Objective To review our experience in the diagnosis and management of paralysis of the right hemidiaphragm after liver transplantation. Methods 60 adult patients received liver transplantation from February 2001 to March 2007 in Sun Yat-sen Memorial Hospital were retrospectively analyzed. The pathophysiologic changes, clinical progress, and management of serious respiratory complications caused by post-transplant paralysis of the right hemidiaphragm were studied. Results Among 60 patients, 40 developed postoperative respiratory complications, and 5 were due to paralysis of the right hemidiaphragm. The 5 patients presented with paradoxical respiration and the ventilator supporting times were 14, 16, 34, 45, and 60 days, respectively. Tracheostomy was performed in 4. These patients developed pneumonia in 5, atelectasis in 4, acute respiratory distress syndrome (ARDS) in 4, hepatopulmonary syndrome in 4, and pulmonay interstitial edema in 3. Among the 5 patients, 4 patients survived and 1 patient died of ARDS and multiple organs failure 31 days after the transplantation. Conclusions After liver transplantation, strict monitoring of the respiratory function and timely use of a respirator for patients with the paralysis of the hemidiaphragm is very important. For patients with suspicious hemidiaphragm paralysis, tracheostomy should be decisively performed.

Objective To investigate the change of HR,RR and arterial blood gas in the treatment of BiPAP ventilation in patients with acute pulmonary.Methods Fifty eight patients with acute pulmonary edema were randomized into two groups.The control group(n =29)were given conventional general treatment only,but treatment group(n =29)were given BiPAP ventilation besides conventional treatment.4 h later,heart rate (HR),respiratory rate(RR),SaO2,pH,PaO2 and PaCO2 were compared between the two groups.Hospitalization duration and incidence of invasive mechanical ventilation were recorded after discharge.Results Compared with pre-treatment,HR,RR,SaO2 and PaO2 in treatment group were improved significantly(HR 124 ± 12 beat/min vs 83 ±6 beat/min,t =5.372,P ＜0.01)(RR 37 ±5 beat/min vs 19 ± 8 beat/min,t =4.285,P ＜0.01)(SaO2 81.4％ ±5.4％ vs94.1％ ±4.2％,t=2.731,P＜0.05)(PaO2 53.2±5.4 mm Hg vs 89.1 ±8.5 mm Hg,t=5.763,P ＜0.O1).And these four indicators were also improved in control group after treatment,(HR 123 ± 10 beat/min vs 95 ± 8 beat/min,t =t =3.459,P ＜ 0.01)(RR 36 ± 7 beat/min vs 24 ± 6 beat/min,t =3.127,P ＜0.01)(SaO2 81.8％ ±5.7％ vs 88.3 ±4.5％％,t =2.314,P ＜0.05)(PaO2 53.5 ±4.6 mm Hg vs 72.8 ±9.5 mm Hg,t =3.756,P ＜0.01).HR,RR,SaO2 and PaO2 in treatment group were more significantly improved than that of control group(P ＜ 0.01 or P ＜ 0.05).Hospitalization duration in treatment group was significantly shorter than that of control group(9 d vs 15 d,t =3.763,P ＜ 0.01).The incidence of invasive ventilation were lower than that of control group too(but P ＞ 0.05.Conclusion These results suggested that BiPAP ventilation can regulate HR RR and blood gas value to accetable levels,shorten hoptipitalization duration and reduce the incidence of invasive ventilation.It is proved to be an effective therapeutic technique in the treatment of acute pulmonary edema patients.

OBJECTIVETo investigate the laws of eighteen incompatible medicaments of the chest pain prescriptions based on association rules mining.

METHODThe database of chest pain prescription was established and then the chest pain prescriptions composed of eighteen incompatible medicaments were screened. The dynasty, couplet medicines, the property and flavor of drugs and preparation form were analyzed with the frequent item sets and corresponding analysis methods.

RESULTEight hundred and fifty chest pain prescriptions were collected, and 88 of them contained eighteen incompatible medicaments, taking 10.3% of all; the applications of ancient and modern chest pain prescriptions containing eighteen incompatible medicaments are significant difference (P < 0.05). Ancient formulas, mainly focus on the eastern jin dynasty and tang dynasty, are more often used than the modern formulas. The most common anti-drugs is on the Fuzi-Pinellia, Chuanwu-Pinellia; the property and flavor of drugs is bitter cold most closely; the decoction of the formulas is mostly used.

CONCLUSIONEighteen incompatible medicaments account for about ten percent of the chest pain prescription, not an uncommon side. There are certain rules for application of anti-drug compatibility to treat chest pain.

Objective To evaluate the value of acoustic radiation force impulse (ARFI) elastography in assessment of nonalcoholic fatty liver disease (NAFLD) and hepatic fibrosis in rats.Methods Models with various degrees of NAFLD severity were conducted in 110 rats by feeding high fat emulsion.The right liver lobe of rat models were processed and embedded in a fabricated gelatin solution to measure the shear wave velocity (SWV) by ARFI.And the other liver lobes were used for histologic assessment.Based on NAFLD activity score (NAS),the final pathologic NAFLD diagnosis were considered as normal group (NAS=0),simple steatosis (SS) group (1≤NAS≤2),borderline (3≤NAS≤4) group and nonalcoholic steatohepatitis (NASH) group (NAS≥5).The diagnostic accuracy of the SWV parameters in evaluating NAFLD severity and fibrosis stages was studied using ROC curves.Results The difference of SWV values among normal group,SS group,borderline group and NASH group was statistically significant (F=31.53,P＜0.001).Taking SWV≥ 2.54 m/s as the diagnostic standard to differentiate normal rats from rats with SS,and SWV≥2.90 m/s to differentiate SS from NASH in rats,the area under ROC curve (AUC) was 0.922 (95％CI [0.871,0.973],P＜0.001) and 0.882 (95％ CI [0.807,0.956],P＜0.001) respectively.The sensitivity and specificity were 93.5 ％ and 100 ％ for differentiating normal and SS groups,83.3 ％ and 84.2 ％ for differentiating SS and NASH groups.Taking SWV≥3.48 m/s as cutoff to predict fibrosis (≥F2 stage),the AUC was 0.963 (95％CI [0.909,1.000],P＜0.001),the sensitivity was 92.9％ and the specificity was 97.6％.Taking SWV≥3.61 m/s as cutoff to predict severe fibrosis (≥F3 stage),the AUC was 0.997 (95％CI [0.990,1.000],P＜0.001),sensitivity was 100％ and specificity was 98.9％.The same high validity was maintained as in the prediction of cirrhosis (F4 stage) with the cutoff as SWV≥4.50 m/s,and the AUC was 0.993 (95％CI [0.982,1.000],P＜0.001),the sensitivity was 100 ％ and the specificity was 96.8％.Conclusion ARFI elastography is a promising method for differentiating the different severity of NAFLD and staging the degree of hepatic fibrosis with NAFLD in rat models.
